Hello, this movie will discuss downed state, the importance of stability with respect to downed state, and the potential importance of fear for countering stability. I say the "potential importance" of fear because it is not yet clear if fear is meant to be a counter to stability or not. The tooltip for stability says that it works against fear but that is not the case in game. IMO, I believe that it is the tooltip that is in error and that ArenaNet does intend for fear to be a counter to stability. Time will tell.
I went through three phases with respect to how I felt about the downed state. In the first BWE, it was "I hate this." In BWE2, it was "Okay, I don't like this but I guess I can put up with it." In BWE3 it was "Hrm, downed state introduces some interesting mechanics and tension to close fights in the game." The dynamic of a fight changes drastically when a player is downed, and the stakes are very high when there are downed players on both sides of a fight. There are mechanics and abilities specifically designed around the downed phase of a fight. Teams and players who chose to ignore those mechanics and abilities will suffer the consequences.
